(LIZ whom, it nm concern,.-

Be it known that 1, WILLIAM G. LIEBIG, a

l citizen of the United States, residing at Def. made from a strand of wire.

' Fig. 12 is a side view of the carrier.

- 14 is a side view of the carrier.

troit, county of Wayne, State of Michigan, have invented a certain new and useful lmprovement in Brush-Making Machines, andl declare the following to be a full, clear, andv exact description of the same, such as will:

enable others skilled in the art to which itv pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. -A This invention relates to brush-making machines.

It has for its object an improved machine in which the bristles constituting' a tuft to be used for the formation of a brush are automatically gathered from a receptacle and carried to the base of the machine, where they are engaged by a staple that is automatically The staple straddling the tuft of bristles is driven into thelbrush-back and the tuft is secured to the bac i.

All the operations of the machine are automatic except the locating of the brush-back in the proper driven into it.

'lhe several parts and details of the Inachinc are shown in the accompanying drawingsin which- Figure 1 is a perspective of the assembled Fig. 2 isa perspective of the wire- The front of the hammer-lever is broken away in this view. Fig. 4 is an elevation showing the hammerlever actuator, carrier-actuator, and anvilactuator. Fig. 5 is a horizontal section through the wire-feeding mechanism.

position to have the staple Fig'. S is a perspecon an enlarged scale, of the plate 2O shown in Fig. 12 and the immediately adjacent portion ofthe carrier.

In this brush-making machine there is contained an adjustable table on which the back Above this is a guide, nozzle-like in form, through whichreciprocates a hammer-plunger that forces down a tuft of bristles through the guide and with the tuft a staple by means of which the bristles are secured to the brushbacle. Above the nozzle is a horizontallyreciprocating anvil, over which is carried the end of a wire from which the staple is made, A wire cutter and staple-former through which the plunger passes and which itself reciprocates vertically in guides is located above the anvil.

- The staple-former is reciprocated by mechanism that is independent of that which actuates the hammer-plunger. Across the path of the hammer-plunger below the stapleformer swings the end of an oscillatory bristle gatherer and carrier which gathers from the face of a mass of bristles held in a suitable box-like receptacle asufiicient quantity of bristles to form a tuft, carries this tuft into the path of the hammer-plunger, where the legs of the staple will straddle the tuft, and over an opening through which the staple and the tuft are forced into the nozzle or guide, and thence into the brush-back. Thesevarious parts are driven in their reciprocations and oscillations by gearing and levers connected therewith that are located behind the head of the machine and which are primarily driven by a master-wheel and are timed to coact properly.

The entire mechanism is driven by a master-wheel A, to whose shaftmotion is given by a clutch-wheel K and clutch k. This motion is given from any convenient source of power and in any convenient way. y

On each face of the master-wheel Ais a cam, and of these the cam 37 act'uates the hammer-plunger lever 7, and the cam 32 on the opposite face of the master-Wheel actuates the lever 2S, which in turn actuates the bristle gatherer and carrier. The gatherer is composed of several parts hung by an arm 40 to a pin 161, that projects fromthe front face of the machine. Y

The master-wheel also drives a ygear 50, that acts as actuator for the mechanism by which the wire is fed under the staple-cutter. The ear in turn drives a cross-sha t 52, upon whic there are cams that actuate the wirecutter lever 11 and the anvil 10.

At the front of the machine rise two posts 71 and 72, which furnish guides for a vertically-reciprocating plunger-head 73, that carries the hammer-plunger 13. The head 73 travels in guides on the opposing faces of the posts 71 and 72. Through the head 73 is an opening through which projects the end of the hammer-actuating lever 7, resting upon an antifriction-roller 74, that is journaled in ears at the forward side of the head 73. From the head above the o enin projects a in 79, that coacts with t e gat erer, as will be hereinafter explained.

The two osts 71 and 72 are carried on the forward e ges of brackets, of which that one which supports the post 71 is seen at 77 in Fig. 1, and do not extend to the base-plate 5 of this part of the machine; but a pair of posts 3 land 300 rise from the base 5 1n substantial alinement with the posts 71 and 72. Between these posts 3 and 300 is a block 6, adapted to reciprocate in the same way as the hammer-plunger 73, but yactuated in its reci rocation by a lever 11. This lever 11 is osci lated by cam 1110 on the shaft 52, the rear end of the lever being lifted by this cam and the forward end being lifted by spring 8,` that reaches from the lever 11 to a hook on the post 72. The block 6 is a wire-cutter and staple-former and cuts the wire 55, fed into position for such cutting by mechanism that will be referred to hereinafter. The block bends the ends of the piece of wire that has been clipped 0H downl over an anvil 10, timed to locate itself under the wire at the time the wire is out and to remain so located until the ends are bent and then to be Withdrawn by cam 120, which is a grooved cam having a groove in the face thereof in which engages an antifriction-roller 101 on the end of the anvil-handle 10. The cam causes the anvil to slide in reciprocation through guides 111 and 112. l

The wire 55 is fed through an opening in the post 3 and through an 4opening in a hardened ni ple 4.- The front of that end ofthe' nipple W -ch extends inward ifrorn tlie post 3 is cut on an incline to produce a long wedge* like or a pointed cut of the wire, suitable to produce a pointed end to the le of the staple. The wire drawn from the reel 57 is carried between the jaws of a gripper device, (which need not be described, as it forms no partof the resent invention.) The grip er is actuate by a cam at the end of the s aft 51 rand is timed to grip the wire, advance it properly with respect to the action of the hammer, and retreat preparatory to a subsequent advance of the wire.

The bristles are gathered bristle-holding receptacle bymeans of a athering and carrying device which oscilates on the stud or pin 161, 'carried by bracket 162 from the post 71.

The carrier is an oscillating member having several parts. TheY main part has two arms 40 and 41 springing from a hub portion 16. The part 40 normally hangs from the hub and sustains at its lowerend a long 4arched foot having a peripheral' length along aboiit three times the northe arch equal to mal oscillation. That part of the foot located on what imay bev considered the forward side of the arm 40 is much longerthan the oppositely-located part and terminates with a somewhat-acutely-pointed toe 18. About one-third ofl the distance along the foot from the toe toward the' heel 21 is a notch 19, extending inwardly from the edge of the carrier and inclining forward toward.

the toe. The extreme toe portion is reinforced and partly formed by a plate 181, i

which is secured 'to the toe part of the carrier by bolts 188, which engage through oval slots in the portion 18, thus permitting adjustment of this plate to vary the width of the notch 19, and, further, in .the' event of its inner end, which forms the acute-angled projection at one side of the notch, being broken off by accidental engagement against a hard substance the remalnin portionof the plate 181, after being remove and sharpened, can be readjusted, so as to make the notch 19 the same size as before the accident, thus obviating the necessity of discarding the entire carrier, which would be a matter of considerably greater expense. A small and easily-adjustable iillerplate 20, provided with a n er 201, (illustrated in detail in Fig. 15,) ma es ossible a variation in the depth of the notch. lfhe plate is held by a bolt extending through its oval center portionr into the body of the peripheral portion ofthe carrier, the finger,

which extends transversely of the eripheral edge, obstructing the notch 19, as i lustrated.

To the rear of the notch 19 and about twofv IIO thirds of the distance between the toe and the heel is acurved indentation or clearanceslots 532rand 58 in the foot 401. 'lhe p ate '78 engages over that part of the carrier which extendsbetween the notch 19 and the indentation or clearance' notch 182 and past it some distance to the rear. of the narrowed portion ofthe plate 78 has a vertical groove 38, which is normally radial from the face of a to the hub of the carrier. y The particular ofr[he forward edge para-lle with the arched edge ofthe foot and Y rising toward' the hub 16.

' 40 as the size of the slots V53 and 58 permit,` and not until the plate 78has under this ac- `with a half-circle extension 61 midway between the' ends ofthe slot and on that` side of the slotv which lies toward the hub 16.` 'IlieV plate 78 between the openings 53 and 58 widens and assumes-ashape somewhat triangular in outline, with the apex of the triangle Near the apex of the triangular part isa stud 25, carrying an antifrictionfroller throuvh which the actuation for the oscillation o? the entire carrier is imparted;y "Ihe plate 78 is adapted, by reason of the construction described, to have not only the swinging motion, duringwhich it ac* companies the main part of the carrier, but-is,

adapted to have also a sliding and oscillating motion upon the main part of the carrier. To this end the pins 54 and 59, which engage through elongated slot-s, permit the plate 7 8v to slit e on and with respect to the main partoi the carrier and to precede it in its advance and in itsretreat for a distance limited by the size 'of tlieslots 53 and 58. It also allows the plate 78 after it has shifted. through a portion of its independent movement to swing on the pin 54-1until the pin 59 engages in the extension .61 otthe slot 58. y

'l he main reciprocating actuation of the carrier iseffected by the engagement of the pin 25 in the horizontal cross-slot 26 in a vertical reciprocating slide 75, which engages in a Ivertical recessed track or groove inV the l'ranie of the machine. Because of its sus* pension' upon the stud or pin 161, which is,

swinging or oscillating motion, which after .some intentional delay -is'coniiiiunicated to the entire carrier, thisdelay. being caused by the fact that when the downward actuation ol the reciprocating slide begins the plate` 78is as near the heel portion 21 ot' the carrier tuat-icn .slid as far forward on the lcarrier as the limits of these slots permit is the pressure upon the pin 25 communicated fully and di rectly to the carrier as a whole. The vertical slide 75 doesnot, however, convey a steady reciprocating motion, but is driven by cam 80,

against which the end ofthe driving-lever 28 is held by the yielding guide 32 during a portion of the revolution of theJ cam.` Durinfr .the time that the cfrier is thus held by en gagement of the afntif'liction-rollei onthe end of the lever 28 between the cam 3() and the yielding guide 32 the yarm 41 of the carrier is nearly to its extreme position, to advance in the direction of the toe part 18 faster than the plate 78, which is not rigid with res ect t0 the body portion of the carrier, resu ting in the opening of the notch 19, which contains. the tutt of bristles. "'I he pin 79 next strikes an incline 84 on the projection- 81 on the other' edge of the branch 41. 'Ihis jolts the carrier sha-r ly, though very slightly as I'e gards actua displacement in the opposite direction until the forward edge 178 ofthe plate 7 8, which faces toward the toe 18 ofthe foot and to vshidiso'me of the motion of the carrier has by thistime been imparted, has engaged against the post 300, so that it'can move no further forward.` 'lhis last movescent o'i the staple. i 'lhe end 38 of the platel 7 8 is grooved, as shown at 38a in Fi 13, and

in the position of the plate 78, just escribed. by the side'of the guide-hole 14 it serves as a guide for the staple 17.

To understand the action of the carrier part of the machine, su pose the hammer to be at the upper end ci) its stroke, the carrier to be retracted, and the plate 78 to be drawn back so that its end 38 1s drawn from over the mouth of they slot 19. In this position the slot 82 inthe plate 78 is drawn back so that it is some hat to the rear of the indentation or clearance-notch 182 in the periphery of the b'dy\ ortion of the carrier. 'lhe carrier-actuator egins to descend before the hammer begins its stroke and moves the'plate until the end 38 closes the mouth of the slot' 19, and the' two together complete their oscillation "until the slot with the bristles in it rests over the hole 14. The

`plate 78 engages' against and is stopped by the post 300, andthe upper end ofthe arm 39 is in osition to allow the pin 79, which is carrie by the reciprocating plunger 78, to engage successively the lugs or projections 83 and 84 hereinbefore described. The hammer-head now begins to descend, the-pin 7 9 engages the lugs, moving the carrier some# iv hat, though still leaving the plate 78 bearing against. the post 300. The stroke of the pin 79 upon the lower projection 84 on the arml 41, as heretofore stated, retracts the arm 40 of the carrier, which then remains at ICO IIS

rest until the plate 78 is retracted to bring the pin 59 directly opposite the extension 61 of the slot 58. The carrieractuator begins to rise, and its first movements lifts the plate 78 radially inward to the limit of the eXtension 61 of the slot 58, after which the carrier Acontinues on its upward travel to complete its swing. j

While the carrier is on its downward stroke and the forward movement of the plate 78 with respect tothe body portion of the carrier has closed the notch 19, it has brought the notch 82 into registering position with respect to the clearance-notch or indenta tion 182, which during the downward movef ment of the carrier becomes 'filled with bristles, which'it gathers from the extreme forward portion 'of the Istore in the feed-box, carrying them downwardly toward the lower and forward edge of the pile in position for most convenient seizure w1thin the notch 19 on the next upward movement of the carrier. When the carrier again swings up with the notch 19, gathering the supply of bristles o for the nextdelivery-stroke o the carrier, that pa of the periphery of the plate 78 Which co Itains the gathering-notch 82 slides with respect to the body portion of the carrier so that it is no longer 1n register with the indentation 182 and with it swings above and entirely clear of the exposed supply of bristles. 'lhis continuation of the upward movement of the carrier causes the pin 59 to slip out ofthey extension 61 of the slot 58, into which it fell during' the first part of the upward movement 'ust described.

VIt will be notice in Figs. 13 and 14 that the peripheral edge ofthe plate 78 is beveled somewhat. 'I'he pu ose of this -is to reduce to a minimum the ictional surface of the engaging edge of the carrier, so. that as ity moves vto and fro against the store of bristles it will disturb as little as possible their transverse position with respect to the edgeof the carrier. 'lhis beveling is not however, so pronounced' as to make the engaging edge in- ]uriously sharp.

. In Fig. 12 1s shown a desirable sectional construction of the carrier, which permits its vbeing composed of several pieces, each of which can be replaced when broken without 'maldng it neeessa to discard the uninjured parts, the angular ine 67 marking the point at which one of these more slender parts 4joins the foot portieri 461 of the earrier.-

Inorder that the 'arm 39 may be properly adjusted to produce theresults, it 1s made in two parts 39 andlhdpivotally connected and with the extreme en of the part 39 engaging between the ad'usting-screws 43 and 44, which are inserte through lugs on the edges of the part 41, and bear against the end of the part. 39. The part 41 carries the projecting cam-lugs and`81 and these can be properly adjusted to coact with the Apin 79 and carrier.

lbristles the wrist-pin 25 and its actuator'to properly time the movements above described. The cam which drives the cross-head inwhich the pin 25 engages is provided with the yieldin guide 32, alreaol referred to, and with a fixe guide 33, the atter of which insures the proper engagement between the roller-bearing 31 and the cam 30 and the former of which, 32, insures an engagement ofthe rollerbearingofthe cam, which, however, may yield slightly against the tension of spring 35, ut which is limited in its movement by a pin 135, that projects from the face of the Wheel and engages in slot 136 in the guide 32.

A rovision for any inequality of friction is empllbyed in connection with the hammerdriving lever 7, the rear end of which is p-on vided with'a hook 57a, that catches or may catch temporarily on the pin 88 on the cam 37 and causes a lifting of the forward end or' sition by a brace 91, that is pinned to lu 921 The bristles are held in a box 60, capa adj ustability as to width and provided with a follower 6a, adapted to push the mass of bristles forward with their front surface constantly in engagementwith the gatherer and f In order that the boX 60 may be adjustable -L for width, the bottom 63 is provided with IGO- ears 63a, that extend toward the sides, and the ears are slotted for the reception of bolts. The

sides 64 are provided with footieces 65,'

through which bolts engage, and t ese bolts engage through the slots in the bottom, so

los

that the sides 64 may be contracted or spread n within the limit of movement determined by the length of the slots 66. The bottom'63 o and the top 67 are each provided with guiderails 68, between which engages the central follower 6, forced forward by a weight hung byl a cord 69,- that passes over sheaves 70. T e top 67 is hinged -to risers 7 and provided at its rforward en d with a pair vof pivoted latches 7 d, by which it isheld to thebottom.

In operation the: gathering of a tuft of plate 78 slides to the limit of its independent is accomplished during the backv y ward stroke ofthe carrier, which sweeps across Atf movement toward the toe of the gatherer,

opening the notch 182 and swinging the 4guard-plate 78 to confine the bristles-that have been gathered in the notch.1`9. During the forward movement the bristles in the notch 19 are carried to the staple. Thev bristles on the face of the receptacle are carrled downward,l tending to accumulate them toward the bottom of the plunger.

There they are left on the next retrograde movement of the carrier to be picked up by the approaching notch 19, and to aid in the assembling of the bristles in this, portion of thereceptacle 6() in a compact mass a movable finger 93 extends centrally forwardl in the receptacle 60 under astrain ofa spring 94,

` Awhich tends to lift the point of it as against the downward pressure of the gatherer in its forward movement. This counteracts the tendency of the bristles to descend too far when .under pressure from the 'vicinity vof notch 182 of the downwardly-descending car rier.

Vto bring a bunch of bristles into place under the staple the staple-forming mechanism and After the gatherer has been oscillated the hammer are forced downward, irst forming a staple above the bunch of bristles, next driving the staple, with the bristles engaged between the legs of it, through the mouth 14 and through theguide 141 and into the brushback on the table 15. i
